Developers love us!

Kernel allows us to run web agents at scale, saving us tens of hours each month from tedious manual form filling. We love it.

Teddy Smyth, Concourse

@teddy_smyth

Kernel is easy to use and immensely powerful. They do the heavy lifting of the technical challenges of web agents, allowing us to focus on other facets of our product.

Richard Ou, Doe

@YuhuangOu

Our team tried many solutions, but Kernel was the only one that worked. With Kernel, our team is able to scale our agentic fraud detection workflows with ease. Thank you!

Nicky Goulimis, Tunic Pay

@tunicpay

I literally just added 5 lines of code to my existing agents and was up and running in under an hour - oh, and it's wicked fast.

Kishan Sripada, Orange Slice

Kernel is solving the difficult problem of fast and reliable computer use infra. The team is experienced and thinking about all the problems in the right ways.

James Sun, Playmatic

@JamesZmSun

Kernel provides a critical infra layer for agentic commerce. Headless browsers will soon be used everywhere just like the shift to cloud computing.
